Renault establishes a new
benchmark in the 2.0-litre
diesel engine class
The 2.0 dCi redefines diesel engine standards.
Powerful, flexible, quiet-running, economical, and environmentally-friendly:
the new 2.0 dCi unit launched by Renault redefines diesel engine standards.
Now available in the 150hp (110kW) version in New Mégane and New Laguna,
and in the 175hp (127kW) version with particulate filter in New Laguna,
this 1995cc unit jointly developed by Renault and Nissan – dubbed M9R –
provides the highest efficiency in its class regardless of power. It combines the
driving enjoyment of a petrol engine with the low fuel consumption of a diesel.
Teamed with a new 6-speed manual gearbox (the PK4), this concentration
of diesel technologies complies with the Euro 4 emissions standard and
features highly developed internal aerodynamics. This allows its piezo-electric
fuel injectors to work in optimum conditions, while various acoustic solutions
ensure unequalled travelling comfort. This engine is equipped with chain-driven
camshafts for the sake of acoustic comfort, but also to the benefit of reliability
and service life.

In its 175hp version, the 2.0 dCi is equipped with a particulate filter.
The 2.0 dCi unit achieves the best power/economy/CO2 emissions trade-off, with
fuel consumption of only 5.4 litres/100km and CO2 emissions of 144g/km in
the 150hp version in New Mégane, 5.8 litres/100km and 154g/km in the 150hp
version in New Laguna, and 6 litres/100km and 159g/km in the 175hp version.
In the coming months, this engine will equip other models in the Renault range.
The level of performance provided by the 2.0 dCi is made possible by the latest generation common-rail fuel system. It injects at a pressure of 1600 bars, which improves the quality of combustion. There are four valves per cylinder for better mixing of air and fuel. This engine features especially advanced internal aerodynamics. The inlet and exhaust ports are positioned “in opposition” in the cylinder head, each camshaft operating both inlet and exhaust valves. Situated on each side of the cylinder, the inlet ports enter the combustion chamber at different angles. This creates a double swirl effect which improves distribution of the air/fuel mixture. Thus disposed, the ports ensure better filling of the cylinder, and better scavenging of the burnt gases.
